How to fix WordPress Allowed memory size exhausted error in websites

INTRODUCTION

In the WordPress sites, the allowed memory size exhausted errors could have been a burning issue that very often occurs as a bolt from the blue sky for the users. However, this memory size limit of WordPress sites is one of the commonest issues encountered among the WordPress site owners. As the WordPress is based on the PHP, the maximum memory that can be allotted to any WordPress site will depend upon the PHP memory limit.

When sufficient memory will not be available for the WordPress site in the server, the log file will show: “fatal error: allowed memory size of XY bytes exhausted in/dir/filename.php on line XY”. The symptoms of this fatal error could either be a blank page or an error message and it is related to PHP configuration of the server.
